Changpung skirmish

The Changpung skirmish (14 October 1949) was a pre-Korean War skirmish between North Korea and the United States. Some US Air Force A-26C Invader planes were attacked by neutral fire from the Korean People's Army near Changpung, resulting in a deterioration of relations between the two nations.

Prelude
The US Army was dispatched to South Korea in 1949 under President Harry Truman, who transitioned all of the United States' military commands in Japan to the disputed South Korean border with North Korea. Truman believed that North Korea was mobilizing its forces, and he was right; he located a massive buildup of Korean People's Army troops on the border when the first US troops arrived.

Skirmish
On 14 October 1949, a squadron of A-26C Invaders received neutral fire from North Korea's units stationed across the border while they stood dangerously close to the 38th Parallel. The gunfire could be heard by the other US units, and the American forces in the region were put on high alert. As a result of the attack on the US military, Secretary of Defense John Moxus reported the incident to President Truman, who considered either ignoring the fight or using it as a pretext for war. Truman decided to ignore the incident, as he did not want to go to war with North Korea over a minor border incident. Just a few days later, the two sides would clash again in the Kaesong skirmish.
